MAX6006–MAX6009 1µA SOT23 Precision Shunt Voltage Reference
Pin Description PIN NAME FUNCTION SOT23 SO
Output Voltage. Bias OUT with a pullup resistor to a potential greater than OUT. Bypass 1 6, 8 OUT OUT to GND with a 0.01µF or larger capacitor. 2 4 GND Ground 3 — IC Internally connected test point. Leave this pin unconnected, or connect to GND. — 1, 2, 3, 5, 7 N.C. No connection. Not internally connected.
Detailed Description Typical Applications
The MAX6006–MAX6009 are precision, two-terminal, In the typical shunt regulator application shown in series bandgap voltage references. On-chip thin-film Figure 1, RBIAS is used to set the current through the resistors are laser trimmed to provide 0.2% output volt- load (IL) and the current through the shunt regulator age accuracies. Voltages of +1.25V, +2.048V, +2.5V, and (IRMIN). There are two worst-case situations that RBIAS +3.0V are available in the space-saving SOT23 package needs to be sized for: (2.1mm 5 2.7mm). 1) RBIAS must be small enough that when VS (supply

In applications maximum and IL is at its minimum, IRMIN is < 2mA. where the load or the supply can experience step changes, additional capacitance will reduce the amount of overshoot (or undershoot) and assist the circuit’s transient response.
Output Voltage Hysteresis
VS Output voltage hysteresis is the change in the output volt- age at T I A = +25°C before and after the device is cycled RMIN + IL RBIAS over its entire operating temperature range. Hysteresis is I caused by differential package stress appearing across L VR V the bandgap core transistors. The temperature hysteresis OUT I value is typically less than 200ppm. RMIN MAX6006 MAX6007
Turn-On Time
MAX6008 The output capacitance and bias current of the MAX6006– MAX6009 MAX6009 greatly affects turn-on settling time. In the R Typical Operating Characteristics, turn-on time is shown BIAS = VS - VR IL + IRMIN with a 10nF output capacitor and a 1.2µA bias current. Under these conditions, the MAX6006–MAX6009 settle Figure 1. Typical Application Circuit in 40ms. Settling time will linearly decrease in proportion to the circuit’s bias current. www.maximintegrated.com Maxim Integrated │ 6
